Communication Connector Wire Holding Member Impedance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication connectors experience reduced communication quality due to impedance changes in exposed wire ends, leading to signal reflection and degradation, especially in high-speed communication applications.
Innovation Solution
A communication connector design featuring a conductive wire holding member with dividing members that surrounds and stabilizes second wires, arranged in diagonal positions within wire rows, to suppress impedance changes and maintain signal integrity, while allowing for a compact and efficient assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wires are exposed at the end part of the cable where coating is removed, then connection to terminals is enabled, but impedance change points are created causing signal reflection and communication quality reduction
Solution Approach 1:
The wire holding member is designed to hold wires at positions where impedance changes are suppressed before signals can be affected. By pre-positioning the wires in a controlled manner within the holding member, the patent prevents impedance fluctuations and signal reflection that would otherwise occur at exposed wire ends, thus counteracting the harmful effect before it impacts communication quality.
Solution Approach 2:
The wire holding member acts as an intermediary component between the exposed wires and the terminals. It provides a structured interface that maintains proper wire positioning and spacing, thereby preventing direct impedance mismatches at the connection point while still enabling reliable electrical connection to the terminals.
2Ease of operation
If multiple terminals are arranged in a single row in the housing, then connection functionality is achieved, but the connector becomes long in the arrangement direction restricting arrangement space
Solution Approach 1:
The patent transitions from a single-row linear arrangement of terminals to a multi-row two-dimensional arrangement. The wire holding member is configured to accommodate wires arranged in multiple rows, allowing terminals to be positioned in corresponding multiple rows within the housing. This dimensional change reduces the length of the connector in the original arrangement direction while maintaining all necessary connection functionalities.

AI summary
A communication connector (30) includes terminals (31) to be connected to wires (12 to 18), including first wires (12, 13) and second wires (14, 15) capable of faster communication than the first wires (12, 13). The wires (12 to 18) form first and second wire rows (22A, 22B). A housing (35) accommodates the terminals (31). A conductive wire holding member (40) holds relative positions of the second wires (14, 15) on one end of the first wire row (22A) in an arrangement direction and the second wires (14, 15) on an opposite end of the second wire row (22B). The wire holding member (40) has dividing members (41A, 41B) configured to surround the second wires (14, 15) when the dividing members (41A, 41B) are assembled.
